10.1.3 Checking your wiring
If the above procedures fail to diagnose the issue you may have a wiring fault. Unplug the
RJ45 from the PIDU+ and check the following resistances at the RJ45:
1. Check the cable resistance between pins 1 & 2, 3 & 6, 4 & 5 and 7 & 8 at the RJ45.
Check against column 2 in
1177HTable 18.
2. Check the cable resistance between pins 1 & 3 at the RJ45. Check against column 3 in
1178HTable 18.
3. Check the cable resistance between pins 4 & 7 at the RJ45. Check against column 4 in
1179HTable 18.
4. Ensure that there is greater than 100K ohms between pins 1 & 8 for all cable lengths.
